Objective(s): This study is looking at the contaminant levels in lake trout and burbot in Great Slave Lake and in arctic char after their return from feeding in the ocean. The West Basin of Great Slave Lake has been chosen because it receives contaminants from the Slave River and the air, and the East Arm has been chosen because fish in this area receive contaminants mostly from the air. Lake trout are most commonly consumed and harvested in this lake and turbot livers can contain high contaminant levels. Char have been chosen because Inuit are being advised to eat more char and less seal, beluga, and walrus in order to reduce the amount of contaminants they consume. This study will determine if contaminant levels in char are the same across the arctic, or higher in some regions than others. In addition, contaminant levels will be measured to see if they have gone up or down since the last measurements were made.
